To (1 whom it may wave rm:

Be it known that I. Fimxn Ti. ivlOl-fF-AN, a citizen of the United States, residing in (in einnati, in the county elf llantilton and State of Ohio, have invented certain new and use- .lul lniprm'ements in 'lvrie-a'iting hlzr chines, of which the following is a specification.

My invention relates to front work-sheet guiding; and gaging; means for tront strihe writing: machines, particularly those in whieh a roller platen has a case-shitting movement.

The invention provides means which serves as a gage shil'tahle with the platen to indicate the position of the writiu; line on the work-sheet while the platen is in both lower and upper use positions; provides a platen scale; and forms a worle 'iiece holder adapted to hold a sheet or \\'oll(piecc in position on the platen atter the lower lle oi the sheet has passed la yen l the usual platen teed rolls, therelrv enahliugthe writing to be carried pra tically to the huttom oi the sheet.

In carrying out the invention. swinging plates or wings ma he mounted on the machine. frame or type-liar segment at opposite sides of the printing point. and caused to hear with a nmderate viehling pix". .ure against the platen er workpiece thereon, a long the writing line and ewing as to indi *ate the position of th lhlllfllil ol the writing line: said plates preteralilv provided with scale graduations at le ter space intervals along: the writing line, To enable the gages to shift up and down with the platen, they l ave an up and down sliding eonneetion with their supports. The. shitting movt-naant of the gages is teller-ted lrv a rod mounted on the platen frame and extending; longitteliuallv at tiaA'platen, and having a lan'izontal sliding eonneetion with said gages which permits the. gages ta remain stationary during th letter teed oi the platen, lint forms a positive means for shifting the gages up and down with the platen (luring the case-shitting movements of the latter, so that the gag s naintain a eonstant.1-elati0n to the. writing line. and ad curately indieate the latter in both upper and lower case posit ;s. The scale plates or gages constantly bear against the platen as they shift therewith, and thus serve to held a worksheet after the lit-thin. elge t-l.

the, latter has passed beyond the platen feed rolls, and. prevent the work-sheet from be coming displaced during the ease-shifting movements of the platen so that the writing may he carried close to the bottom of the sheet. Said seale plates further serve for holding cards, envelops and other small \YUI'lil-PlOCtS on the platen. As the said. plates bear against the face of the workpiece along" the printing line, the usual tendency of a stiff card, or other small workpiece to spring away from the platen along the printing line is overcome, and the workpiece held firmly against the platen at the printing point, enabling clear type impressions to he made.

In some 'nachines the rising scale plates, if shil'tahle to upper-ease position througl out the entire range of the carriage travel, wnuhl ha it to be made short to prevent them from striking the carriage frame when the arriage is near ither limit of its travel, or the ronstruetion oi" the machine might be such as to preclude the use of rising scale plates with the carriage near its limits of travel. The present invention provides means whereby sueh interference may be avoided. and the scale plates in practice materle lv lengthened, thereby increasing their eil'ertiwnws and usefulness To this end, means pmvidtal for preventing each scale plate from being shifted up or held up with the platen when the adja ent end of the earriage has heen brought within striking range of the scale plate. For this purpose, the supporting rod on the carriage which shifts the scale. plates up and down, is made of such len l that each scale plate will run off the rod when the, end of the carriage approaches the scale plate, allowing the latter to drop it innpper-case position, and pre- V911 Plug it from rising if the platen is shifted up while the ea :riage end is within range of the scale plate. To further assist in this operation, arms may be provided on the earriage, one adjacent each end of said rod, to swing the scale plates oil the rod. Said cams further serve to hold the scale plates away from the platen, so that. when a worksheet is shifted up and down with the platen while the hottmn edge of the sheet is near the printing line, the 'zale plate held away from the platen will not eateh on the corner of the work-slice; the platen is slatted up and den. a Said rains also protect the usual.

I hit;

.1 the wing,

a sin"- Emma gated openings in said arms 47, this eonneetion permitting adjustment oi the rod 45 to accurately adjust the rising srale plates to the line of writing. The rod 4.3 enters grooves 49 in the guide-Moths if said hloehs sliding along the rod during the movement of the platen in the direction of its length and operating positively to lift the seale plates 37. 38 with the platen to the Fig. 1 position, when the platen is shifted to uppercase position. In other words, the shitting scale plates maintain a lined rel tion to the platen during its ase'shitting movements. It will thus be seen that the position ol the writing line accurately lorated when the platen is in upper-ease position as well as when in lower-ease position.

As the seale plates shift with the platen, they are adapted to hold in position on the platen the lower edge ol' a work-sheet that has loeen l ed lit )]l(l the usual platen let-d rolls, so that the writing may he rurried very rlose to the bottom of the work heet. The soale plates prevent the work-sheet from slipping or becoming displaced as the platen shifts up and down: the seale plates ,mzty also serve as card-holders l'or maintaining Cards. envelops, and the like in position on the platen.

In the machine illustrated. the rising seale plates 37, lil. il maintained in upper-ro e position, would inh-rl'ere with ihe lrame ends 50 of the earriago as the latte! nears its limit of travel in either direrlion. in other words, the lrame ends 5v) (Fig. ll extend across the path ol' travel ol' the srale plates. The present invention provide; means tor automatirally dropping eaeh ol vaid plates as it is appromhul h the rarriage from, so that sueh interl'erem'e avoided without unduly shortening the alt: plat s.

To permit the scale plates to drop at the proper time, the supporting rod ll; terminates at surh points that. as either seale plate approaehes the ('arriage l'rame, the (-or responding guidedrloel; lil slides oll said rod and permits the plate to be thrown down by its spring 42. To l'urtlier assist in the release of the plate from the rod l3, rams .T are located adjacent the ends ot the rod. These cams may he seeured to paper guiding extensions 53 of the paper shell .34, and lie in the path of the guideddorlrs iii, and op erate positively to fort-e the seal plates outward or away from the platen a i-ullieient distance to release them trom the supporting rod 45. Thus, in Fig. 2. the carriage is near the limit of its movement to he right. and the wing 37 has been moved into pos tion to he thrown outward from the platen by the cam 51, (see also Fig. l), and thrown by its spring 42 to lower-ease position in which it will not interfere with the carriage as the latter is moved to the limit of its travel. to

the right,

In Fl 5 the parts shown in the position assumed just prior to the release of the wing 25? by the cam 51. As here shown, the cam has been brought up to the guide-hloek l5, and an v further movement 01' the carriage to the right will cause the cam to force said hloeli l, outward and release it from the supportmg rod 45 and permit the wing to drop. m

The righthand wing 38 is released in like manner as the carriage approaches the limit of its movement to the left. The cam plates il serve not only to release the Wings 37. 38, and permit them to drop, hut also hold said wings away from the platen, so that they eannot eateh on the lower edge of a worksheetwhen the platen is shifted up and down while said edge of the work-sheet is elose to the printing line. The rain plates 51 also serve to protert the usual trout platen teed rolls 5.3 from being robbed by the wings 37, 2% during the travel ol the earriage.

Variations may he resorted to within the seope of the invention, and portions of the improvements may he used without others.

Having thus deserihed my invention, I claim:
